No. 674,486 Int. Cl. B26b 13/24 U.S. Cl. 30-133 3 Claims ABSTRACT OF THE DISCLOSURE A device for removing cuttings from the area adjacent the cutting portions of a pair of scissors, including a suction head secured to one of the scissor members, and a vacuum hose connected to the suction head.

SUMMARY OF THE INVENTION The usual procedures of cutting and thinning hair with a pair of scissors present a problem with regard to the disposal of the cuttings. While the application of suction equipment to remove cuttings from machinery if various types is a general practice, no practical applications of this principle are known to applicant which would have the effect of removing hair cuttings without obstructing the cuttting procedure. Equipment embodying this invention is constructed to be light in weight, and is secured directly to the scissors so that the application of suction is at all times applied to a point where the cuttings are produced. In the preferred form of the invention, the suction head attached to the scissors is secured directly to one of the articulating scissor members in such a manner as to establish the relative alignment between the cutting portion of the scissors and a recess in the head to which vacuum is applied. A dual use of the pivot pin of the scissors as a means of securing the scissors to the vacuum head produces the simplest form of the structure. The preferred form of the invention also includes a configuration of the suction head which facilitates the cutting procedure, rather than obstructing it. A shelf provided along one side of the opening in the suction head can be used as a basis of controlling and inspecting the hair before and during cutting operation. This shelf permits a portion of the hair to be lifted directly adjacent the suction opening so that a clear view is had of the un-cut hair, with all of the adjacent cuttings being removed so that the inspection procedure is not confused by the presence of cuttings.

DETAILED DESCRIPTION The several features of the invention will be analyzed in detail through a discussion of the particular embodiments illustrated in the accompanying drawings. In the drawings:

FIGURE 1 is a view showing the manner in which the device is held by the barber during the cutting operation along the side area of the customers head.

FIGURE 2 shows the manner in which the device is used in working on the back of the head.

FIGURE 3 shows the use of the device in picking up stray cuttings which may have fallen during any previous cutting operations.

Referring to FIGURES 1 through 10, the device 20 is shown connected to the suction hose 21, with the device being secured to the scissor member 22. The scissors generally indicated at 23 are held in the right hand 24 of the barber, whose left hand 25 carries the comb 26 in the usual manner. The scissors 23 are formed by the articulating members 22 and 27, which are pivotally interconnected by the screw pin 28. The scissors members 23 and 27 are each provided with the handle portions 29 and 30, respectively, and with the cutting portions 31 and 32.

The suction head 20 has a portion defining a recess 33. This recess has an opening with the upper edge 34, the lower edge 35, and the opposite end edges 36 and 37. A shelf or flange 38 extends with the face 39 in generally coplanar relationship with the opening of the recess 33. The tubular extension 40 defines a passage 41 communicating with the recess 33, and forms a point of connection for the hose 21. so that vacuum can be applied to the recess 33.

The portion of the suction head defining the recess 33 is provided with a lateral extension 42 having a formation in the face 43 for receiving the portion of the scissors member 22 adjacent the pivot pin 28. This arrangement establishes the alignment of the cutting portion 32 with respect to the edges 34 and 35 of the recess opening. FIG- URE 6 shows the configuration of the portion 44 which receives the cutting member 22. When the scissors and the vacuum head are assembled as shown in FIGURE 4, and connected to the hose 21, the result is a light-weight system that applies vacuum to the area immediately adjacent the cutting area of a standard pair of scissors, without requiring modification of the scissors beyond the provision of a special pivot pin, and without obstructing the functioning of the scissors during the normal cutting operations.

The modification of the invention shown in FIGURES 11 through 14 utilizes a suction head 45- which is generally similar in configuration to the head 20 described previously. In the modified arrangement, however, the scissor member 46 is secured to the face 47 by a screw 48 which does not function as a pivot pin. The scissor member 49 is pivotally connected to the opposite scissor member 46 by the separate pivot pin, or screw 50. If desired, the screw 50 may additionally engage the face 47 of the suction head to participate in securing the scissor member 46, with the two spaced screws being utilized to secure the alignment of the scissor member 46 with respect to the edges of the opening 51, in place of the surface 44 shown in FIGURE 6. Provision for this latter arrangement is shown in FIGURE 12, which shows the two threaded openings 52 and 53 for receiving the screws 48 and 50, respectively. It should be noted that the use of the surface 44 will normally require that the area indicated at 54 in FIGURE 6 be raised above the plane of the opening in order to embrace the lower scissor member in the manner shown in FIGURE 8. In both modifications of the invention, the axis of the connection 40, and the portions of the suction head defining the conduit rpassage fll, are arranged on anaxis perpendicular i to the plane of articulation of the scissor members 31-32 and 46-49. This relationship produces the result best shown in FIGURE 1, in which the hose 21 is conveniently supported by the right arm 55 of the operator, which places the hose in a position where it does not interfere with his vision as he proceeds with the cutting operation.

In these claims, it is my intent to claim the entire invention disclosed herein, except as I am limited by the prior art.

I claim:

1. In combination with a pair of scissors including opposite members each having handle and cutting portions, said members being pivota lly interconnected with a fulcrum pin, a collecting device comprising:

a head having a recess extending along the cutting portion of one of said members, said head being normally secured to said one member with said fulcrum pin, said head also having a passage communicating with said recess; and

.vacuum means normally connected to said head in communication with said passage.

2. A device as defined in claim 1, wherein said head has a lateral extension provided with a formation receiving a portion of said one'rnember to establish relative alignment. 7

3. A device as defined in claim 1, wherein said one member cutting portion extends along one edge of the opening of said recess, and the opposite edge thereof is provided with a shelf portion substantially coplanar with said Opening, and extending away from said recess.
